   生产环境一数据库服务器(SQL Server 2014)的Agent服务突然停掉了，检查了错误日志,发现在"SQL Server Agent"里面没有"SQLServerAgent terminated (normally)"的信息，只有如下错误信息

 

根据作业运行的日志信息，以及上面错误信息，可以判断SQL SERVER Agent服务应该在2016-04-24 9:20: PM（21:20）异常停止了。在“Windows Logs”下的“System”日志下，有如下错误信息，我们可以确定SQL Agent在这个时间点异常结束了，但是从这些信息还不知道发生了什么导致SQL Agent服务异常终止。

The SQL Server Agent (MSSQLSERVER) service terminated unexpectedly.  It has done this 1 time(s).

 

在“Windows Logs”下的“Application”可以看到更详细的错误信息

The description for Event ID 17052 from source MSSQLSERVER cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

SQLServerAgent Monitor failed to restart SQLServerAgent after SQLServerAgent terminated unexpectedly (reason: SQLSCMControl() returned error 5, 'Access is denied.').

the message resource is present but the message is not found in the string/message table

 

在C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Log里面发现这个时间点生成了SQLDUMPER_ERRORLOG.log和SQLDmpr0001.mdmp

根据这里红色部分信息判断，应该是内存收缩（memory shrunk）导致的。追查到此处，是什么具体操作导致，已经无法判断，追查。特此记录一下这个案例。
